Filed Dec. 4, 1961, Ser. No. 156,840 18 Claims. (Cl. 26-514) This invention relates to a Weatherstrip and sash balance for slidable sash type of windows and stops therefor.

The principal objects of this invention are:

First, to provide a Weatherstrip and counterbalance means including stop means limiting the opening movement of the sash.

Second, to provide a Weatherstrip assembly with stop means constituting a unitary assembly for shipment, storage and installation.

Third, to provide a Weatherstrip stop means which may be mounted on the Weatherstrip in retracted position and projected into casing engaging position without tools.

Fourth, to provide a stop means for sash slideways of the outwardly facing channel way type which is formed of a single piece of sheet metal stock.

Objects relating to details and economies of the invention will appear from the description to follow. The in vention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. 1 is a perspective view including a window frame upper and lower sash and weatherstrips and stop units embodying our invention, certain of the parts being broken away to show the relation thereof, and certain parts being shown conventionally.

FIG. 2 is a fragmentary view in vertical section with parts broken away to show structural details and relation of parts of the assembly of FIG. 1.

FIG. 3 is an inside View of a slide rail or member with stops of our invention embodied therein and shown in retracted position by full lines and parts thereof in projected position by dotted lines, parts of the Weatherstrip as such being shown conventionally.

FIG. 4 is an enlarged fragmentary view partially in section illustrating a stop in installed relation to the Weatherstrip and a sill.

PEG. 5 is an enlarged fragmentary cross-sectional view on a line corresponding to line 55 of FIG. 3 illustrating its installed relationship of a stop member to the weatherstrip.

FIG. 6 is a fragmentary perspective view of a stop member embodying our invention.

FIG. 7 is a fragmentary view on a line corresponding to line 77 of FIG. 6 illustrating structural details or features of the stop.

FIG. 8 is an enlarged fragmentary view of one flange oi the combined Weatherstrip and sash slide member.

In the accompanying drawing, 1-1 represents the stiles of a window frame, 2 the sill and 3 the frame top member.

hese are conventionally shown and joints or connections therefor are not illustrated. The numeral 4 represents a lower sash and 5 an upper sash; 6 represents a lock for the sash. These parts are also conventionally illustrated.

Like weatherstrips are provided for the stiles of the casing or frame, only one being illustrated but it will be understood that they are designed to face oppositely. The Weatherstrip designated generally by the numeral 7 is formed of a strip of sheet metal conformed to provide a central parting strip 8 and forwardly projecting flanges 9 on both longitudinal edges thereof which coact with the parting strip to form sash slideways 19. The edges 11 of the flanges 9 are folded inwardly and in the preferred embodiment, see FIG. 8, initially spaced from the flange and springably yielding relative thereto, see FIG. 8.

The counterbalance springs 13 when in retracted position being within the housings 14 are provided with sash engaging members 15.

The opening movement of both the upper and lower sash is limited by the sash stops and these are duplicates, one being engaged with the outer slideway flange at its lower end and constitutes a stop for the upper sash, and the other being disposed at the upper end of the slideway for the inner sash to limit the opening movement thereof.

The embodiment of our stop unit illustrated, which is a commercial embodiment, comprises the body portion designated by the numeral 16 of outwardly facing chan nel section and comprises the web portion 17, inner arm 13 and outer arm li which has an inwardly or rearwardiy projecting flange 20 spaced therefrom to receive the outer flange Q of the slideway, see FIGS. 4, 5, 6 and 7.

The springable tongue 21 is disposed transversely of and struck out from the outer arm 1?, the tongue forming slits extending into the web portion at 22, see FIG. 4. This springable tongue frictionally and retainingly engages the weatherstrip flange 9 when the stop is in assembled relation with the Weatherstrip, see PEG. 5, and serves to slidably retain the stop on the Weatherstrip so that the stop can be assembled therewith in retracted position as shown in FIG. 3 for merchandising as a unit and also for installing as a unit.

The arm 13 of the stop is provided with an inturned flange 23 which serves to provide a finished edge and also as a stiffening means. It will be noted by reference to FIGS. 5 and 6 that the stop members have smooth exposed edges.

At its upper end, the stop member is provided with a sash seat member 24 which is an integral part being a laterally turned upper end portion of the arm 1? and being supportingly engaged with the upper end of the Web and the arm 13, see FIGS. 6 and 7. This provides a sash seat member or abutment for the sash.

The bight portion 17 in the embodiment illustrated is provided with a tongue 25 having teeth 26 on its side edges. When the rail is completely installed, the tongue is embedded into the sill or the top casing member, PEG. 4, illustrating the tongue embedded in the sill. With this arrangement of parts, the stops may be assembled with the slideways as a unit, as illustrated in FIG. 3, the slideways installed and the stops prongs driven or forced into the casing merely by means of manipulation of the sash. Of course ey could be seated or driven in by means of a tool but no tool procedure is necessary.

As has been pointed out the inturned edges 11 of the flanges 9 are in the preferred embodiment, see FIG. 8, spaced from the body portion 9 of the flanges so that they coact with the springs 21 in holding the stops in retracted position, as shown in full lines in FIG. 3, and in preventing tilting thereof relative to the weartherstrip, see the c-oacti-ng relation therewith of the inturned tongue 21, FIG. 5.

Ordinarily the rails are secured by fasteners inserted through the hole indicated at 2-7, FIG. 1, which serve double purpose of anchoring the rails and securing the counterbalance housing d4.

We have illustrated and described our invention a highly practical and desirable embodiment thereof. We have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt our invention as may be desired to meet particular requirements of frame or casing structure and sash. The sash illustrated is of wood frame type as is also the easing. As stated, these parts are conventionally shown as the details thereof form no part or" our present invention.

Having thus described the invent-ion, what is claimed as new and desired to secure by Letters Patent is:
